This season, we explored large-scale climate interventions that could be our last hope. One intervention in particular, solar geoengineering, made a lot of listeners’ heads spin. (We’re right there with you.)

This episode, we answer some of your most pressing questions about solar geoengineering. We get into whether solar sunshades could harm crops, what international efforts around solar geoengineering look like, and what would happen if a powerful country went rogue and put sulfur dioxide into the stratosphere. Plus, we look at a solution to some of these more extreme solutions: decarbonizing.
